AMERICAN HOME PRODUCTS CORPORATION By:_________________________________ Title:______________________________ ONCOGENE SCIENCE, INC. By:_________________________________ Title:______________________________ -15- 17 EXHIBIT 1 ANNUAL SPONSORED RESEARCH PLAN FOR COMMITMENT YEARS 1 AND 2 OF THE WYETH-AYERST/ONCOGENE SCIENCE COLLABORATIVE RESEARCH AGREEMENT 18 1. Executive Summary Oncogene Science has developed a proprietary gene transcription-based technology to identify new drug leads. A summary reviewing the advantages of gene transcription as an approach to drug discovery is attached in Appendix 1. A collaboration with Wyeth-Ayerst Research is proposed to exploit this technology in order to develop drugs in four therapeutic areas: non-insulin dependent diabetes, immunomodulation, asthma, and osteoporosis. The immediate goal is to identify small molecular weight compounds which specifically modulate the transcription of four target genes *** thereby either increasing or decreasing the concentration of the corresponding protein product. ***. *** *** *** These portions deleted pursuant to a request for confidential treatment. -2- 19 2. Program Overview Oncogene Science has developed a unique drug discovery technology specifically designed to identify compounds which affect the transcription of target genes. Once a particular gene has been chosen as a target, the next step of the process is to clone the regions of DNA which regulate expression of that gene. These sequences are then fused to a highly sensitive reporter gene (the firefly luciferase gene) which generates a readily measurable signal in response to changes in transcription of the target gene. This genetically engineered DNA construct is then introduced into an appropriate cell type and stable lines isolated. Such cell lines will generate a signal which reflects a change in gene expression when an appropriate compound is added to the tissue culture media. Lead identification is based upon very highthroughput drug screening, ie., screening up to 100,000 compounds or fermentation broths against each target in a single year. To achieve this, a fully automated screening system has been developed using state-of-the-art robotics developed at Oncogene Science. Complete automation not only allows the primary screen to be cost effective, but has proved essential to obtain highly quantitative and reproducible data from a transcription based screen of this type. Each robotic system can analyze several thousand samples per week against multiple target genes. By using multiple targets in the primary screen, activity, cytotoxicity, and initial gene specificity can be evaluated rapidly. ***. Compounds which are active in the primary screen are immediately retested to establish an EC(50)/cytotoxicity index. Automated on-line data reduction and statistical analysis allows rapid quantitative determination to identify the initial lead compounds. Complete data sets and lists of lead compounds can be provided in a format compatible with Wyeth Ayerst's existing data analysis system. ***. Appropriate tertiary assays and animal models can then be employed for the later stages of lead development, and typically would be conducted at Wyeth-Ayerst. *** *** *** *** These portions deleted pursuant to a request for confidential treatment. -3- 20 *** *** *** These portions deleted pursuant to a request for confidential treatment. -4- 21 3.

This requirement shall be deemed satisfied with respect to any specific Target area if Wyeth is developing any Human Therapeutic Product in that Target area. Such development will be shown by semi-annual progress reports which demonstrate that the Human Therapeutic Product remains an active candidate for filing in an Investigational New Drug Application with the U.S. Food and Drug Administration. Wyeth shall have an exclusive license to all Human Therapeutic Products arising from the Collaborative Research Program in a Target Area so long as it satisfies its development obligation with respect to any specific Target area as provided for in this Section 2.4.1. 2.4.2 In the event that, in the course of its development of a Human Therapeutic Product as provided for in Section 2.5.1, it becomes apparent, in Wyeth's determination, that a Product or Products will not be commercially viable, the parties agree to the following disposition of such Product or Products: a) if the determination arises during or after the term of the Collaborative Research Agreement, and the Product or Products are not the sole development candidates in a specific Target area, the Product or Products shall remain exclusively licensed to Wyeth; b) if the determination arises after expiration of the Collaborative Research Agreement and if the Products are the sole development candidate or candidates in a specific Target area, OSI shall have the option to an exclusive license thereto, including the right to -21- 38 grant sublicenses, under Wyeth Patent Rights and Wyeth Technology on terms to be negotiated mutually by the parties. 2.5 Technical Assistance.

No royalties on Net Sales shall be payable on sales transactions between or among Wyeth and its Affiliates; the final vendee sale to a third party alone shall be used for the purpose of determining the royalty payments due hereunder. The Licensed Human Therapeutic Product subject to royalty payment shall be deemed sold when invoiced, or if not invoiced, when the same shall be shipped or delivered to the third party. All taxes, assessments and fees of any nature levied or incurred on account of any payments accruing under this Agreement, by national, state or local governments, will be assumed and paid by Wyeth except taxes levied thereon as income to OSI and if such taxes are required to be withheld by Wyeth, they will be deducted from such payments due to OSI and will be paid by Wyeth for the account of OSI, and a receipt therefor secured and sent to OSI. 3.5 Records. Wyeth shall keep for three (3) years from the date of each payment of royalties complete and accurate records of sales by Wyeth of each Licensed Human Therapeutic Product in sufficient detail to allow the accruing royalties to be determined accurately. OSI shall have the right for a period of three (3) years after receiving any report or statement with respect to royalties due and payable to appoint at its expense an independent certified public accountant reasonably acceptable to Wyeth to inspect the relevant records of Wyeth to verify -23- 40 such report or statement. Wyeth shall make its records available for inspection by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice from OSI, to the extent reasonably necessary to verify the accuracy of the reports and payments. Such inspection right shall not be exercised more than once in any calendar year nor more than once with respect to sales in any given period. OSI agrees to hold in strict confidence all information concerning royalty payments and reports, and all information learned in the course of any audit or inspection, except to the extent it is necessary for OSI to reveal such information in order to enforce its rights under this Agreement or if disclosure is required by law. The failure of OSI to request verification of any report or statement during said three-year period shall be considered acceptance of the accuracy of such report, and Wyeth shall have no obligation to maintain records pertaining to such report or statement beyond said three-year period. The results of the inspection shall be binding on both parties. 4.

Wyeth agrees to defend, protect, indemnify and hold harmless OSI from and against any liability, claim, loss, cost or expense arising from any claim for liability based upon Wyeth's manufacture, use or sale of any Licensed Human Therapeutic Product. 4.4 Third Party License. If the manufacture, use or sale by Wyeth of a Licensed Human Therapeutic Product would, in the opinion of both Wyeth and OSI, infringe a patent owned by a third party, Wyeth and OSI shall attempt to obtain a license under such patent. If Wyeth obtains a license under such patent, (fifty) percent (50%) of any payments made by Wyeth to such third party shall be deductible from royalty payments due from Wyeth to OSI pursuant to this Agreement; provided, however, that in no event shall royalties payable to OSI be reduced by more than twenty-five percent (25%) as a result of all such deductions. All such computations, payments, and adjustments shall be on a patent by patent basis. If OSI is of the opinion that such manufacture, use or sale would not infringe such patent owned by a third party, OSI may, at its election, bring suit against such third party seeking a declaration -28- 45 that such patent is invalid or not infringed by Wyeth's manufacture, use or sale of the Licensed Human Therapeutic Product involved, or may bring opposition, nullity or other proceedings against such patent, as appropriate. If OSI is successful in such suit, Wyeth shall continue to pay royalties in such country as provided in Section 3. If OSI is unsuccessful in such suit, it shall join Wyeth in an attempt to obtain a license under such patent, and fifty percent (50%) of any payments made by Wyeth to such third party for such license shall be deductible from royalty payments due from Wyeth to OSI as to that patent pursuant to this Agreement. 5. Termination by Wyeth Wyeth may terminate this Agreement at any time without cause by giving OSI at least six (6) months notice prior to the termination date.
